Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiments of the invention are described in detail.
The present invention includes nozzle 43, rifle body 1, cavity seat 5, trigger 7 and motor 8, described cavity seat is arranged on the front portion of described rifle body, and described nozzle is arranged on the front end of cavity seat.In described cavity seat, be provided with cylinder sleeve 5-3, needle 4 can slide in cylinder sleeve.One end of trigger connecting rod 61 is provided with protruding 61-1, described projection can with the fit depressions of fork 6 one end.The other end of described fork is also swingingly fixed on cavity seat 5 through the slotted eye on needle 4.The other end of described trigger connecting rod is provided with hole, and the boss that this hole extends with trigger 7 matches, thus trigger connecting rod and trigger 7 can be made to link together.The middle part boss 61-2 of trigger connecting rod, through the bar shape trench hole on motor 8 housing, the cylinder between described middle part boss 61-2 and electric machine casing overlaps and has back-moving spring 62.
Slidably quick-release button 63 is provided with at the bearing of trend of the protruding 61-1 of trigger connecting rod.Described quick-release button comprises a cylinder, " L " shape groove 63-1 is provided with at described cylindrical outer surface, described " L " shape groove can match with the spacing preiection 1-2 on rifle body, can not rotate to guarantee quick-release button can only slide in its cannelure, as long as and turn and can not vertically moving in lateral circumferential groove.The described cylindrical bottom of quick-release button is also provided with a boss 63-2.The end 63-2 of described quick-release button contacts with the boss 61-2 in the middle part of trigger connecting rod.Described trigger is provided with adjusting knob 71, adjusting knob is paid trigger by screw thread and is connected.
Above described rifle body, be provided with Liquid storage container 2, the liquid outlet 21 of described Liquid storage container is connected with described cylinder sleeve 5-3.Container cover 3 is connected with cavity seat by breather line 32.The side that breather line is positioned at container cover is provided with check valve 31.Between container cover and Liquid storage container, be provided with sealing ring, between needle and cylinder sleeve, be provided with sealing ring 5-4.The top of rifle body is provided with U-shaped fixture 5-1, and the front end of Liquid storage container is fixed by the both sides of described U-shaped fixture.The rearward end of described Liquid storage container is provided with catching groove, and this catching groove can match with the hasp 9 that rifle body rear end is provided with.The inner side of described rifle body front end is provided with the track 1-1 of two symmetries, cavity seat two outside be provided with the convex tendon 5-2 matched with described track.The optimum angle of the plane that the motor back cover 82 of rifle body afterbody and handle end are formed and Liquid storage container oral area axis is 70 degree, to ensure that spray gun feed liquid benefit be unlikely in Liquid storage container on placement ground or other planes goes out.
When Liquid storage container and cavity seat thereof need be installed, the quick-release button 63 be positioned on rifle body is rotated to unlocking condition, then the convex tendon 5-2 on outside cavity seat is aimed at the guide rail 1-1 of rifle body leading inside, utilize the guide effect of guide rail, one end of cavity seat 5 is advanced the leading inside of rifle body 1.When the end thereof contacts of the leading section of fork 6 and trigger connecting rod 61, the protruding 61-1 in one end due to trigger connecting rod is designed to inclined-plane (as shown in Figure 3), under the acting in conjunction of back-moving spring 62, the groove of fork 6 leading section and the protruding 61-1 of trigger connecting rod can be made to be fastened togather, rifle body rear end hasp 9 to be fastened in the catching groove of Liquid storage container rear end simultaneously.Now, Liquid storage container and cavity seat thereof install on rifle body.For preventing spray gun generation misoperation, can, by quick-release button rotation 90 degree to locking state, the spacing preiection 1-2 on rifle body be entered in the lateral circumferential groove of quick-release button from the cannelure of quick-release button.Now, the boss 63-2 of quick-release button bottom extends the end side surface of the middle part boss 61-2 of trigger connecting rod the sixth of the twelve Earthly Branches, even if malfunction trigger 7, but can not move left and right because boss 63-2 limits trigger connecting rod the sixth of the twelve Earthly Branches, making it fork can not drive needle 4 to do corresponding movement, and therefore spray gun cannot work.When needing operation, can will unload button opposite direction 90-degree rotation to unlocking condition, now the boss 63-2 of quick-release button bottom removes the restriction to boss in the middle part of trigger connecting rod, as long as pull trigger 7, motor is just energized and carries out work, air compressing is entered cavity seat 5 by check valve 10 and enters in Liquid storage container by breather line 32, simultaneously by trigger connecting rod 61, fork 61 is driven to swing backward, because fork is through the slotted eye on needle 4, thus valve needle moves backward, the feed liquid in Liquid storage container is made to enter in cylinder sleeve by inlet 21, again from the gap ejection formed between needle and cylinder sleeve.The feed liquid sprayed from nozzle 43 mixes with from conjugating the air-flow that tuyere 41 sprays and is atomized.Displacement tuyere 4 is arranged on the front end of cylinder sleeve 5-3 by nut, rotate displacement tuyere 41 and just can obtain different liquid aerosolization shapes.When spray gun quits work, needle is valve nozzles outlet under the effect of back-moving spring 44.For ease of regulating the size of feed liquid quantity for spray, trigger is provided with adjusting knob 71, the displacement being controlled trigger by adjusting knob reaches the displacement of control needle in cylinder sleeve.
If Liquid storage container and cavity seat thereof need be disassembled from rifle body, can by quick-release button rotation to unlocking condition, then quick-release button 63 is pressed, just the protruding 61-1 of trigger interlinking lever end departs from the engaging of fork 6 leading section groove, removes the engaging of rifle body rear end hasp 9 and Liquid storage container rear end catching groove simultaneously.Now, Liquid storage container and cavity seat thereof can be separated from rifle body.Operate very convenient.
